中文摘要	气相色谱法研究小分子溶剂与聚合物材料之间的相互作用是一种快速、准确、方便的方法 ,该方法可以用来研究多种小分子溶剂在聚合物中的溶解和扩散行为 .通过气相色谱法测定了 3种小分子烷烃溶剂(正庚烷、正壬烷和正癸烷 )在固定液聚乙烯中的保留时间和半峰宽 ,用 van Deemter模型进行数据处理 ,得到 3种小分子在聚乙烯膜中的无限稀释扩散系数 .; Gas chromatography is a new, fast, accurate and convenient technique for studying the relationship between small molecule solvents and polymer membrane materials. Many parameters of dissolution and diffusing characters of a small molecule in a polymer can be measured by this method. The rentention time and the peak width at half-height of three small molecule solvents (n-heptane , n-nonane and n-decane) in the stationary phase of polyethylene were measured. The diffusion coefficients of the small molecule solvents at infinite dilution were calculated with van Deemter equations. The graphs plotted according to the results of the diffusion coefficients of the three solvents at infinite dilution vs. temperature were in agreement with the Arrhenius equation. The variance in the diffusion coefficients at infinite dilution of the three small molecule solvents was analyzed according to the differences in molecular mass.; 国家自然科学基金 (批准号 :2 0 2 760 3 4); 国家“八六三”计划项目 (批准号 :2 0 0 3 AA3 2 80 2 0 ); 国家“九七三”计划项目(批准号 :2 0 0 3 CB615 70 1)资助
